Application led December This invention relates to ahumidifyingapparatus with which may be useda spray device Whieh is improvedincertain particulars. The object of this invention is to provide a 5humidifier which is susceptible of accurate control whereby to produce adesired moisture content in a given body of air, and also to simplify toa considerable extent the spray device used in connection therewith,soas to break up into exceedingly small particles the water which supplieshumidity to the air.

An exemplification of this invention is set forth in the accompanyingdrawing in the manner following:

Referring particularly to Figs. 1 to 4, the spray device therein showncomprises two units, a rotor A and a stator B. The rotor may consistof'a casting having a pair of 3 spaced parallel walls 10 and 11 whichextend angularly from'ahub 12 after the manner of a shallow cone'.vConnecting the two walls and extendingbetween them are radial vanes 14which proceed inwardly from the periphof the spray eries'of the walls toa point substantially half.

way toward the center of the` rotor. The inj ner ends 15 of the vanesare'curved to one side, and all in Vthe same direction, as shown best inFig. 2. The outer wall 10 is provided centlally with an axial sleeve 16wherein is re- 50 ceived one end of a. driving shaft 17 to which therotor is fixed'ly connected. On its inner side the wall 10 is alsocurved forwardly to an axial point 18 in general conformity with thecurvature 19 which joins the inner wall 55 11 with the hub 12.

Theouter wall of the rotor is shown as having its periphery extendedslightly beyond that of the inner wall. By this arrangement I am enabledto mount on the periphery of the outer wall a band 20 which carries' aplurality of wings 21 extending across the ends of the vanes 14. Betweenthese wings and the periphery of the inner wall 1l is a space suiiicientfor the accommo- 65 dation of a complementary set of wings 22 whichlextend laterally from a second band 23 having a mounting on the statorthe form o1 which is preferably that of a spider plate, as f shown. Thearms of the stator are joined to a iange 24 upstanding from a bearingbox 25 in which is journaled the hub 12 of the rotor. Any suitable meansfor providing a water-tight joint between the hub of the rotor and .itsbearing may be used, sunch as the packing 26 and gland 27. i

From the lower side of the bearing box is extended a nipple 28 inconnection withvan intake pipe 29 through which water is taken in to thespray device. Rotation of the shaft 17 causes the rotor to be revolvedwith a consequent turning movement of the vanes 14 and outer wings 21.The direction of the rotor movement is as indicated by the arrow in Fig.2. A suction effect is thereby created sufficientto draw through thepipe 29 water` which is standing at a lower level. The water so takeninto the rotor is advanced by. centrifugal force to the peripherythereof where it is discharged rst against the inner wings 22 which arestationary with the stator.' After being broken up into ne particles,the water is then acted upon by the outer Wings 21 which furthercomminute and break up the water particles. Thus in the condition of avery fine spray the water is discharged from the device.

A spray device having these characteristics may be used with advantagein a humidifierl is taken over a body of water 35 which is containedwithin a t'ank at the bottom of the cabinet. Over this tankis mounted aspray device which may be the same as the construc-4 tion shown anddescribed in connection with Figs. 1 to 4 inclusive; The bearing box 25of this sprayer may be connected to one or more struts 36 by whichadditional support is af-A forded thereto. The inlet pipe 29 is shown asdepending intothe water body so as to draw its suppl therefrom. Ifdesired, a thermostatic va ve 37 may be interposed in the feed pipe. Asupply pipe 38 is also provided in connection with the tank containingthis water, and, if desired, a float valve 39 may be connected therewithto maintain the body of water at a selected level.

Rearwardly of the spray device are water eliminators 40 which mayconveniently comprise a series aof closely arranged parallel plateshaving corrugations or angularities, as shown best in Fig. 5. Themoisture-laden airleaving the sprayer is required to pass between theseplates which segregate water particles of 'excess size, causing same todrain into the tank at the cabinet bottom. Rearwardly of the watereliminators, I have shown a second heater 41 to which is con-v nectedinlet and outlet pipes 42 and 43, respectively. This heater may be ofthe same general construction as the' heater 32 al-v readydescribed. s

The rotor shaft .17 extends outwardly from the cabinet through a secondhousing 45 wherein is mounted a rotary fan 50. The shaft carries nearits outer end a pulley 46 over which a driving belt 47 may run to impartmotion which is received from a power shaft 48. Extending from the fanhousing 45 is a duct 49 whlch leads to one or more places wherethe-moisture-laden air is to be used.

The humidifier of this invention is advantageous because of thesimplicity of itsY construction, and because of the complete used forthis purpose may be supplemented,

as necessary, from an outside source, its inflow being controlled by theoat valve 39. The air which is taken into the humidifier is Itreated andconditioned by the several units which act upon it so as to be renvderedsuitable, both as to temperature and moisture content, for any selectedpurpose.
